A Novel Latch-Up-Immune DDSCR Used for 12 V Applications

In this paper, a high holding voltage dual-directional silicon-controlled rectifier (SCR) with an embedded shunt path (HVDDSCR-ESP) for high-voltage I/O electrostatic discharge (ESD) protection is proposed. Based on the 0.13-μm BCD process, multi-current pulses that mimic the transmission line pulse (TLP) are applied to devices by using Sentaurus-TCAD. The results reveal that the proposed structur...
